Next, regarding the store visit point processing of the present embodiment, the flowchart of FIG. 14 showing store visit point processing by the information provision control unit 35 of the information providing device 6 and the store visit point processing by the server control unit 41 of the member server 8 are shown. This will be described with reference to the flowchart of FIG. The information providing device 6 acquires the store visit point plan file F8 from the member server 8 via the store computer 4 at the time of activation, for example, and stores it in the memory unit 36.
[0033]
In the information providing device 6, as shown in FIG. 14, the card reader / writer 33 waits for the card read, that is, the acquisition of the member number from the member card (N in S10). When the customer inserts the member card into the card reader / writer 33 of the information providing device 6, the member number is obtained from the member card (Y in S10), and the member server 8 side through the store computer 4 using the member number as a key. An inquiry about information such as accumulated points and member level is made (S11). The inquiry information includes information on the store visit point grant flag. The store visit point grant flag is a flag for managing store point grant once a day, and is set when a store visit point is granted, and is cleared, for example, when the store is closed or when the date is changed.
[0034]
Upon receiving this information inquiry, as shown in FIG. 15, the member server 8 recognizes that it is an information inquiry about accumulated points, member level, etc. (Y in S30), and the member performance based on the inquired member number The file F5, the member level file F7, etc. are searched, and information such as accumulated points and member levels corresponding to the member number is specified and read (S31). Here, the function as the sales contribution level specifying means is executed, and a part of the function as the sales contribution level determining means is executed. Thereafter, a message including data related to the read accumulated points, member level, store visit point grant flag, etc. is set (S32), and the message is transmitted to the inquired information providing apparatus 6 and responded (S33). .
[0035]
As shown in FIG. 14, in the information providing apparatus 6 that inquires about information such as the accumulated points and the member level, after receiving the response, the presence / absence of the store visit point grant, that is, the state of the store visit point grant flag is determined (S12), If it is determined that the store visit point grant flag is set (Y in S12), the store end point has already been granted, and the process ends.
[0036]
When it is determined that the store visit point grant flag is not set (N in S12), the store visit point plan file F8 stored in the memory unit 36 of the information providing device 6 based on the member level transmitted from the member server 8 is used. Then, the winning probability is specified (S13). Here, the function as the winning probability specifying means is executed, and a part of the function as the winning probability determining means is executed. For example, when the member level is level 5 and the business day of the store is 2002/07/05, level 5 in the first summer 1 (plan name) of 1001 (plan number) based on the store visit plan file F8. Of 85% is set as the winning probability.

When winning (Y in S15), a random number from 1 to 5 is generated and an equal prize distribution is calculated to execute an equal prize distribution (1 to 5 prizes). Based on the award, a store visit point to be given to the customer is set based on the store visit plan project file F8 stored in the memory unit 36 of the information providing device 6 (S16). For example, when the equal prize set by the equal prize distribution calculation is the second prize and the business day of the store is 2002/07/05, 1001 (plan number) is set based on the store point plan file F8. The award point 30 of the second prize in the first summer (plan name) is set as a store visit point to be given to the customer.
[0038]
In the case of a loss (N in S15), based on the store visit plan file F8 stored in the memory unit 36 of the information providing device 6, the 6th prize (defeat) award point is set as a store visit point to be given to the customer. (S17). For example, if the store's business day is 2002/07/05, the 6th prize award point 5 in the first summer (plan name) 1001 (plan number) is given to the customer based on the store point plan file F8. It is set as a store visit point to be granted.
[0039]
Thereafter, the member number acquired in step S10 is used as a key, and the member server 8 is inquired of cumulative point update via the store computer 4 (S18). At this time, the store visit point to be given to the customer set in step S16 or step S17 is also transmitted to the member server 8.
[0040]
Upon receiving this cumulative point update inquiry, the member server 8 recognizes that this is an accumulated point update inquiry (Y in S34), and the member result file is based on the inquired member number, as shown in FIG. F5 is searched, and the store results file F5 is updated by accumulating the store visit points in the member results file F5, and the updated accumulated points are read (S35). Thereafter, a message including data related to the read accumulated points and the like is set (S36), and the message is transmitted to the inquired information providing apparatus 6 and responded (S37).
[0041]
As shown in FIG. 14, the information providing apparatus 6 that inquired the cumulative point update determines whether or not the cumulative point update has been normally performed (S 19), and the cumulative point update has been normally performed. When a response is received (Y in S19), a lottery game, for example, a slot game is started based on the equal prize set in step S16 or step S17 (S20). 31 (S21), and the process ends.
[0042]
If it is determined in step S19 that the accumulated point has not been updated normally (N in S19), an error screen is displayed on the display device 31 (S22), and the card reader / writer 33 is sent to the customer as the operator. Is inserted, and the process returns to step S10 and waits for the card reader / writer 33 to read the card again.
[0043]
